Specification of Letters Patent. Patented A11g.,25, 1914:.

. Application filedApril is, 1914. Serial 1%. Banana 1 To all whom it may concern:

Be it known that I, THADDEUS D. ALLEN,

' a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, new and useful Improvements in Automobile-Springs; and I do declare the following to be a full, clear, and exact description 0 the invention, such as will enable others.

skilled in the art to which it appertains to" N f the body and thevout'er ends 'theree fiihave-the This invention relates tonew and useful I improvements in make and use the same.

vehicle springs an; [more especially to springs for 1186113. connection with automobiles and the primary object of the invention is to provide a device of-this character which will eliminate the use of the large and cumbersome elliptical spring. this form of spring being a coiled .spring which is considerably cheaper and equallyns if not more eflicient than the? springs" new in use on automobiles.

A further object oftheinveiitionresides in providing such a coilspringstructure as will afford not alone a suspension means tor the body of the Y ,vehitle on the -axlegiiybut which will also" act shoclr L, fab'sorb'er.

reduced upper ends are threaded as shown therefor. 1

,.With these and other objects in view invention consists'i'n the semireatment any preferred type,

' mobile body I adapted for support above an- 65.

construction, combination and arrangement of parts as will behereinafter referredto and more partipularlyi-pointed out in the specification and claims. 1

In the accompanying drawing forming part of this application zfFigure 1 is a rear elevation of ayehicle showing a device constructed in accordance with my invention applied to use thereon Fig. 2 is a section therethrough as seen on 1ine2--2, Fig. 1;? and, Fig. 3 is a detail perspective view of one of the spring supports removed.

In describing the invention I shall characters designate corresponding 1 indicates a vehicle body of the 1isual or I having shown an auto y in the oflicial drawing, the same being axle 2 which has the wheels 3- suitably mounted at the endsjthereof, in-the' usual have invented certain refer to the drawing in whichsimilar reference parts throughout the several views and in which e q pla'nebf andfdisposedalso through openings in the plates 11 and.* 5'.-, These outwardly extendor any preferred manner. My improved device contemplates the provision of suspension meansbetween the axlennd the body. wh ch suspension: means will, in addition to acting as the-ordinaryspring for. the body of the vehicle, also actas a shock absorber.

To this end pro videa supporting bar or the like & WhlQlLilSbCllI'fidtO theunder face -o:t the. body-in any ;;preferred 1 manner the ends of whichlproject beyond thesides' of T-shaped head pieces 5 fornied iith ereon.

This bar/l is as shownlimthe drawing;

,cured \transverselygofi the body so lthatfthe head p1eces5 project-longitudinallythereef andtformed-centrally on each of said head pieces '5 isyavertically extending sleeve or bearmg 6 which projects above and belowl each. P1886 5 the greater; extending p'ortion. being disposed abovesaiclhad pieced? I Secured tothe axle-2 adjacentjeanh end thereof through the medium of stamping member indicated as 7 is a vertically extends ing post 8, saidposts being guided-through the sleeves or bearings 6 above I'Gfl'lddftt).

The upper endsof said posts 8 are :re duced in thickness to provide shoulders 9 and these at lOiti'nddisposed'through openings in additional plates or strips 11 the latter being of'the same size as the head pieces 5 on the ends of the'bar 4:. Nuts 12 are engaged with the threaded ends 10 of said posts 8, and

when turned home said nuts secure the "plates or strips 11 in position with respect to said posts.

Thus it will be seen that on each side of the vehicle body 1 adjacent the ends of the axlei is provided a frame formed by the s acedupart istripsori lates 11 and. 5 and disposedbetween each pair'of plates is a 'pair' 'i 'iicoil springs f'l3/one spring being ,disp'o'sed'on each sidepteach post 8. The

ind/coils of each/pair of coil springs 13 has the free ends thereof bent inwardly and tiihce'out'wardly-as indicated at 14 these outwardly bent portions extending in the l tllfi longitudinal centers thereof mg ends 141st the end coils of the springs a 18 are threaded and engaged with nuts 15 the-latter obviously securing said springs to the plates and also securing the latter in position "with. respect'to one another. a

It will be seen mm this construction thatnecessary when the device is used in com nection with automobiles. It will also be seenthat the device is simple and durable in construction, extremely inexpensive to manufacture and one which will be very efficient in use.

While I have particularly described the elements best adapted to perform the functionsset forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to, within the scope of the appended claims, without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described my invention, what j I claim 1s:

1. In a device of the class described, the combination with a body and an axle there below; of a transverse bar stcured to said body and having longitudinally extending strips at the ends thereof, vertically extending arms carried on said axle adjacent the ends thereof and guided loosely through said strips, additional strips carried on the upper ends of said arms and coil springs secured between said strips 1 2. In a device of the class described, the combination with the body of a vehicle and-an axle; of a transverse bar secured to the under face of said body and projecting beyond the sides thereof, the ends of, said bar terminating in longitudinal strips, vertically extending bearings formed centrally of said strips, arms removably secured to said axle adjacent the ends thereof-and slidably disposed through the aforesaid bearings, additional strips carried on the upper ends of said arms and coil springs secured between said strips on opposite sides of said arms and bearings.

3. In a device of the class described, the

combination with a vehicle body'of an axle therefor; of a transverse bar secured to the body and projecting beyond the sides thereof, the ends of said bars terminatin in longitudinal strips, vertically disposed bearings formed centrally of said strips and projecting above and below the same, the upper portion projecting to a greater degree than the lower portion thereof, vertically extending arms removably secured to said axle adjacentthe ends thereof and guided through, said bearings, additional strips removably secured to the upper ends of said arms in alinement with the aforesaid strips, and coil springs removably secured between said strips on opposite sides of said bearings and arms.

4. In a device of the class described, the combination with a body and an axle therefor; of a transverse bar secured to the under face of said body and projecting beyond the sides thereof, the ends of said bar terminating in longitudinal strips, vertically extended bearings formed centrally of said strips and projecting above and below the same, the upper projecting portion extending to a greater degree than the lower projecting portion thereof, vertically extending bars removably secured to said axle adjacent the ends thereof and loosely disposed through said bearings, an additional strip removably secured to, the upper end of each arm in alinement with the strip therebelow,

coil springs disposed between said strips on opposite sides of said bearings, the end coils of said springs having the ends thereof bent and disposed loosely through said strips, the last mentionedportions ofsaid coils being threaded, and nuts engaged with the threaded portions of said springs whereby to secure the latter in position between said.
